Enhanced modular drawer structures, systems, and methods

Abstract

A modular drawer structure comprises a housing having an interior volume defined therein, and a drawer comprising one or more compartments, wherein the drawer is slidably movable with respect to the interior volume of the housing between a first closed position, wherein the compartments are enclosed within the interior volume, and a second open position, wherein the compartments are at least partially accessible. The drawer structure further comprises a mechanism for controllably locking the drawer in the first closed position, an access pad, e.g. such as but not limited to a keypad and / or a card swipe pad, for entry of a passcode, and a processor for unlocking the drawer when an entered passcode matches a stored passcode value. Some embodiments of the drawer structure include a stored time threshold, wherein if the drawer is unlocked for a time that meets or exceeds the stored time threshold, the drawer is relocked.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of drawer structures. More particularly, the present invention relates to improved modular drawer structures and associated processes that may be implemented for dispensing within a medical environment.BACKGROUND OF THE INVENTION[0002]Dispensing cabinets, cassettes and trays are often used to for any of storage, transportation, or distribution of medications, such as within a hospital environment. FIG. 1 is a perspective view of a simplified tray 10, such as comprising a tray structure 12, e.g. having an exemplary length 14, width 16, and height 18. The tray 12 has an interior region 20 defined therein, wherein a divider system 22 may be installed or defined therein, such as comprising one or more panels 24 and connectors 26, to create a plurality of storage compartments 30, e.g. 30a-30k, within the interior region 20 of the tray 12.[0003]Automated dispensing cabinets (ADCs) have been used for several years withi...

AI Technical Summary

Benefits of technology

The patent is for a drawer structure that has a mechanism for securely locking and accessing its compartments. The structure also includes a time threshold to ensure that the drawer automatically locks after a set amount of time if someone has accessed it without a passcode. The technical effect of this invention is to provide a secure and convenient way to access drawer contents while ensuring that they are only accessible when desired.

Problems solved by technology

Such carts and cabinets are required to be replenished by a hospital pharmacy, are inherently limited in their storage capacity, and are often not adequately mobile to move from room to room.

While it is often preferred that a nurse transports medications for administration to a single patient at a time, such as due to concerns for safety, this requires a great deal of time and travel for a nurse.

While some institutions forbid this, as it increases the risk of administering the wrong medication, other institutions allow the simultaneous storage and transport of medications for multiple patients.

The simplified tray 10 seen in FIG. 1, such as when placed on a cart for transportation to a patient, does not inherently provide security for the contents that may be carried within, wherein contents may readily fall out, be stolen, and / or tampered with.

Such an inherently low level of security at any point during a workflow process, such as seen in FIG. 2, can pose undue risk to the patient or to others.

As well, caregivers are frequently interrupted during their process of accessing, transporting, and / or administering medications, and often have to find or locate a second nurse to verify administration, such as for a high-risk drug, thus increasing the risk further.

However, keys are easily lost, and do not provide any traceability to individual users.

While some prior carts have included keyless entry for one or more standard drawers, such drawers are not configured to be removable, and when used for dispensing medications, require a separate tray or cassette to be stored within and removed therefrom, e.g. such as a tray 10 as seen in FIG. 1.
